Call to Prayers (Adhaan)
Bukhari :: Book 1 :: Volume 11 :: Hadith 676
Narrated Anas bin Malik:
I never prayed behind any Imam a prayer lighter and more perfect than that behind the Prophet and he used to cut short the prayer whenever he heard the cries of a child lest he should put the child's mother to trial.
